IMIIIIIIIIIIHIII!! E III All my coin will not be received 10 of the disk to prevent reverse rotation of the disk. Arm 17 is also fulcrumed on the frame 1, pin 21, being provided therefor, and it isspring pressed into engagement with the disk by spring 22. This arm is provided with suitable detents on each end, indicated at 24-25. Through suitable connections to be described the movement imparted to the actuating member, and the disk, is transmitted to the delivery mechanism.

As illustrated the frame 2 is suitably counter-sunk or recessed to leave a space between it and the inner surface of the casing sufficient for accommodating the coin of proper width. The insertion of a proper coin through the opening 28 of the casing into the slot 9 of the coin disk Will displace the stop pins 14 and 14'; the coin as it is being inserted pressing these pins back, by engaging their upper inclined surfaces, thereby releasing the stop shoulder 11 to permit rotation of the disk. If the coin is of insufficient thickness it will be unable to sufficiently depress these stop pins 14 and 14 to effect this release. 1f too thick the within the slot. 1f a washer of the proper size and thickness is inserted the second or right hand pin 14 of Fig. 3 will engage the washer within the perforation thereof as will be readily understood and thereby prevent further ro`,

tation. When so released by a coin of the proper thickness the disk may be rotated in the direction of the arrow and if the coin is of the proper diameter it will force the detent 20 outwardly and prevent it from engaging the stop shoulder 11 of the disk. If the coin is of lesser diameter the engagement of shoulder 11 with the detent 2O will prevent further movement of the disk and y reason of the inclined surfaces of the pins 14 and 14 the disk may be returned to lnitial position of Fig. 3 and the improper coin removed. The coin slot 23 determines the maximum diameter and thickness of the coin which can be inserted in the machine. The proper release of the detent 20 from engagement with shoulder 11 by a coin of proper diameter permits of the further rotation of the disk for delivery of the coin into the machine and the actuating member may then be given a full revolution until the stop pins 14 and 14 again register with the coin slot 8. It is designed that when so revolved it will e'ect the delivery of one article as hereinafter described.

Immediately after the coin has been prop erly tested as to diameter by the detent 20 further advance rotation of the disk will advance the rear edge of shoulder 11 beyond the detent 20 which will then co-act therewith to prevent reverse rotation of the disk .and thereafter the detent will similarly coact with the teeth 10 for the same purpose. The detent 24 is adapted to supplement the detent 2O in preventing reverse movement `by coaction with the teeth 10 and shoulder 11 as will be readily seen. When the coin disk has made one-half revolution the slot thereof will be in inverted position so that the coin can drop to either side of platc38 into the bottom of the casing. If, however, a coin of dished or indented form tends, by frictional engagement with the sides of the coin passageway, to remain within the coinslot and continue to revolve the double detent arm 17 will come into action in the manner shown in Fig. S. As there indicated in its progress toward completing a revolution the coin will engage and force outwardly the detent 24v thereby moving the detent 25 into position for engagement with a tooth 10 which will effectively lock the machine against continued operation until the defective coin is removed. When so locked and during the operation with one coin the edge of the coin disk will prevent the insertion of additional coins until the slot again assumes its initial position.

Delivery mechanism. The actuating mechanism is positively connected for operating the delivery mechanism for deliv ering the articles as now to be described. The pinion 4 of the actuating member meshes with an annular intermediate gear member 30 journaled upon an enlarged stud bearing portion 31 of the frame 1 and the gear 30 in turn meshes with a pinion 32 of a delivery member. The pinion 32 is here shown again as large as the pinion 4 and is aiiiXed to a turntable member 34 suitably journaled in the frame. As shown the frame 1 is formed with an annular bearing recess 35 for the turn table 34 which is clamped in position by a flanged bearing collar 36 itself secured in position by screw stud 37 threaded to a supporting and coin defiecting plate 38 as shown; the latter plate being secured to the frame by screws 39-39. The pinion 32 and the turntable are locked together by inwardly extending pins 40 carried by the former. As here shown three of the pins 40 are provided and a further purpose of these pins is to support and position the delivery carrier or drum 43 which is provided with apertures ,at one side to receive the pins and thereby couple the drum to the turntable, to rotate therewith. The frame plate, as shown, is provided with a flange 45 at the top and sides thereof, thereby forming a magazine for the articles above Ithe carrier-drum which closes the bottom thereof. The lower part of the flange 45 is curved substantially concentric with the delivery drum so as to coact therewith in forming a delivery way for the articles which terminates in a side delivery opening 46 through the casing. For closin 'the back of the magazine a thin metal bac plate 48 1s provided with a key slot fitted to the carrier and side flange 45. This tendency headed .inner end ofthe stud 37 whereby it is held in place in a manner permitting usual flat cake form. As is Areadily understood the cakes will drop into the recesses bygravity andas the carrier is rotated they will be delivered therefrom through the delivery opening 46. 1n the double recess carrier shown a single article will be delivered for eaehhalf turncf tlrercarrier and the connections will impart a half turn to the carrier for each complete revolution ofthe actuating member and coin disk described.

A valuable feature of our improved ma chine consists in the arrangement here shown of a double compartment magazine from which there. results an increase in the capacity of the machine. As shown,` thereA is provided acentral. vertical'division wall 52 arranged to be inserted in suitable holding, recesses in the frame l for dividing the magazine intothe -two compartments. Tn operation the articles will be emptied from the right hand compartment of Fig. 1

before any of the articles lwill bey removed from the left hand compartment. This action necessarily occurs by reason of the nearest cake entering therecesses 50 and supporting the succeeding cakes as they pass thereunder. However, to successfully operate in this manner we have arranged for insuring against the cakes within the left hand chute assuming an interfering position with respect to the carrier. Aswill be appreciated, there will bea tendency for the cakes in each of the chutes to tilt into a position vapproaching a tangent to the pev riphery of the carrier and this tendency as associated with the left hand chute tends toward excessive tilting of the cakes into a wedging position in the angle between the to excessive tilting is particularly manifest during the removal of the lowermost cake owing to the action of its flat upper surface upon the cakes above it. This we have overcome by providing a spring pressed suppleinental'side plate 54 for said chute, fulcrumed at 55 and pressed inwardly by a fiat spring 56 bearing against the side flange of the frame. The supporting pressure thus )reduced tends to sustain the pile of cakes 1n substantially horizontal position within this left hand chute during the removal of the lowermost cake. The vaction of the plate is vcontrolled by its' engagement withv the drum which is operative to pressback the side plate for releasing the lowermost cake at the proper time to permit it to enter the recesses 50 for delivery5 and is cut away at 58 to permit gripping of the remaining cakes thereby during the intervalv of removal from beneath the column of cakes above. This arrangement thus effectively prevents the described wedging of the cakes and permits of the double chute arrangement shown.

As indicated the plate 54 is formed with a seat or shoulder at 60 adapted to engage with the corner shoulder 61 of the carrier ywhen the machine is empty thereby to lock the machine against operation without delivery. When so locked the coin disk will not have advanced beyond possibility of reverse movement thereby permitting return of the coin. The presence of the cakes within the recesses during their delivery normally withholds the plate from so en gaging the carrier. This additional locking :function performedby the plate 54 thus makes it essential to the operations of the machine that the article -be delivered.

Our improved arrangement for attaching the machine to seats is particularly effective in securing the machine against unauthorized removal and in permitting rapid detaching of the machine entire for inspection and recharging. To this end there is provided a chair plate 65 Ihaving' perforatedbosses 66 to offset the plate 65 from the surfaceto which it is attached and to receive the usual securing screws 67 whereby it is permanentlysecured `in position.- The machine is securedv to this chair plate in a manner so as to inclose it thereby giving access to the securing screws only upon removal of the machine. As shown the casing flange 69 is fitted over a small turned over flange of the plate and the bottom rear edge of the ,casing flange is formed with upturned lips 70 which are inserted from beneath to underlie the chair plate when fitting the casing over the plate as shown. When so positioned a suitable locking element 76 is arranged to engage apertures Y2-72 in the chair plate so as to positively lock it in position.

An advertising plate 93 is shown attached tothe top of the casing and in accorda-nce with our invention this lplate is extended rearwardly to close the space behind the chair plate thereby to prevent getting at the locking hooks from above with a View to forcing the lock'. As indicated the plate 93 is provided with suitable headed pins to enter key slots therefor in the top flanges of the casing whereby it is clamped thereto by a sliding movement. A small shoulder is formed on the under side of the plate to be engaged by alug 94 struck up from the casing flange thereby to lock the plate against removal when moved into its clamping position.

A further desirable feature is here. shown in Fig. 2 wherein the means for attaching the frame and casing together consists of screw studs 97 and nuts 98 thereon, the studs ybeing provided with squared shoulders 99 fitted to similar apertures in the casing to prevent their being turned from without.

The arrangement as described permits of readily detaching the machine in its entirety which is decidedlyadvantageous for conveniently reloading the machines when `positioned upon the backs of theater seats where owing to limitation of room. and poor light great difficulties would attend this operation particularly in the handling of quantities of the small one cent articles as here contemplated. The arrangement described likewise provides for convenience in removal of the frame and parts thereon for inspection of the coin control mechanism as the coin release mechanism andthe delivery mechanismv are self contained upon the frame member and separable from the actuating member similarly carried. by the and not in a limiting sense.
